This is the second K&N I have bought and definitely won't be the last, due to fast shipping and noticeable difference in performance. I fitted one to my 2005 Mazda 3 2.0L petrol and it has brought the engine to life, the car pulls much better and I find myself staying in higher gears which gives me more miles per tank. I would definitely recomend this product and I will fit one to all my cars in future.
